Q
What are transceiver cables?
A
Transceiver cables are integrated assemblies combining optical or copper cables with built-in transceiver modules to enable direct high-speed network connections between devices.
Q
How do transceiver cables work?
A
Transceiver cables convert electrical signals into optical signals (and vice versa) within a single assembly, streamlining data transmission between switches, routers, and servers.
Q
What types of transceiver cables are available?
A
Common types include direct attach copper (DAC), active optical cables (AOC), and MPO/MTP breakout assemblies, each tailored for specific data rates and distance requirements.
Q
What is the difference between single-mode and multimode transceiver cables?
A
Single-mode cables use a 9 µm core for long-haul links up to 10 km, while multimode cables use 50/62.5 µm cores for shorter runs up to 550 m.
Q
How do I choose the right transceiver cable for my network?
A
Select based on required data rate, distance, connector type (SFP, SFP+, QSFP), and compatibility with your switch or router’s specifications.
Q
What is the maximum reach of transceiver cables?
A
Reach varies by type: passive DAC up to 7 m, AOC up to 100 m at 10 Gbps, and single-mode optical cables up to 10 km or more.
Q
Are transceiver cables hot-swappable?
A
Yes, most SFP, SFP+, and QSFP transceiver cables support hot swapping, enabling replacements without powering down network equipment.
Q
How do I install a transceiver cable?
A
Insert the transceiver module into the port until it clicks, then firmly connect the cable to the peer module or device port.
Q
Can I mix transceiver cable brands with network switches?
A
Yes, if both comply with MSA standards, but always verify compatibility against your switch vendor’s interoperability list to avoid link issues.
Q
How should I clean transceiver cable connectors?
A
Use lint-free wipes with isopropyl alcohol or dedicated fiber optic cleaning tools to remove dust and contaminants without harming the ferrule.
Q
How do I troubleshoot transceiver cable connectivity issues?
A
Check port LEDs, confirm speed/duplex settings, test with a known-good cable or loopback adapter, and inspect connectors for damage or contamination.
Q
What data rates do transceiver cables support?
A
Transceiver cables support speeds from 1 Gbps (SFP) up to 400 Gbps (QSFP-DD), depending on form factor and module technology.
Q
What is the difference between SFP, SFP+, and QSFP transceiver cables?
A
SFP supports up to 4 Gbps, SFP+ up to 10 Gbps, and QSFP up to 40/100 Gbps, each using distinct form factors and port densities.
Q
What are active optical cables (AOC) vs direct attach copper (DAC)?
A
AOCs use fiber with integrated transceivers for longer, lower-power links, while DACs use copper conductors for cost-effective, short-distance connections.
Q
Are transceiver cables MSA compliant?
A
High-quality transceiver cables adhere to Multi-Source Agreement (MSA) specifications, ensuring interoperability and consistent performance across vendors.
Q
How can I verify transceiver cable compatibility?
A
Review your device’s supported module list, confirm MSA compliance, and match form factor, data rate, and wavelength to your equipment’s requirements.
Q
What is the typical warranty for transceiver cables?
A
Warranties vary by manufacturer but commonly range from one to five years, covering material defects and workmanship under normal operating conditions.
